The controller of the touch display 2571 may receive the selection operation, generate a control instruction for the stylus detection apparatus 231 in response to the selection operation, and transmit the control instruction to the stylus detection apparatus 231 to instruct the stylus detection apparatus 231 to switch from the current operation mode to the target operation mode corresponding to the selection operation. For example, when the user clicks a normal operation mode selected from the threshold correction operation mode (i.e., the detection threshold adjustable mode) and the normal operation mode (i.e., the detection threshold fixed mode) displayed on the interface as shown in fig. 3, the controller may control the stylus detecting device 231 to switch to the normal operation mode.

The stylus detecting device 231 may include a plurality of operation modes (e.g., a normal operation mode, a threshold correction operation mode, etc.), and the detection threshold of the stylus detecting device 231 in different operation modes may be different. The detection threshold of the stylus detection device 231 in the normal working mode is an initial detection threshold set by a factory. The detection threshold of the stylus detection device 231 in the threshold correction operation mode can be adjusted and corrected by the user.

The detection threshold is an index for determining whether the stylus is placed in the accommodating device 232, for example, the stylus detecting device 231 is an infrared detecting device, and the detection threshold includes an infrared light intensity value upper limit and an infrared light intensity value lower limit, and if the infrared light intensity value detected by the infrared detecting device is greater than the infrared light intensity value upper limit, it indicates that the stylus has been placed in the accommodating device 232, and if the infrared light intensity value detected by the infrared detecting device is less than the infrared light intensity value lower limit, it indicates that the stylus has been taken out of the accommodating device 232.

In some embodiments, the user's selection operations include, but are not limited to: single click, double click, long press, sliding, etc.

In some embodiments, the display device further includes a remote controller, and the user's selection operation further includes an operation of selecting an option displayed on the touch display 2571 through the remote controller by the user.

Where a remote control means a component of a display device, the electronic device can be controlled, typically wirelessly, over a short distance. Typically, the electronic device is connected to the electronic device using infrared and/or Radio Frequency (RF) signals and/or bluetooth, and may also include functional modules such as WiFi, wireless USB, bluetooth, motion sensors, etc. For example: the hand-held touch remote controller replaces most of the physical built-in hard keys in a general remote control device with a user interface in a touch display 2571.

In some embodiments, as shown in FIG. 4, the stylus detection apparatus 231 may include a micro control unit (Microcontroller Unit; MCU) and a SENSOR (SENSOR) between which communication may be established via an I2C bus. The controller of the touch display 2571 may include a System On Chip (SOC). The SOC may be electrically connected to the MCU through a General-purpose input/output (GPIO) port, and specifically, the GPIO port of the SOC may include GPIO1 (hereinafter referred to as IO 1) and GPIO2 (hereinafter referred to as IO 2), and the MCU may also include one GPIO1 and one GPIO2. The GPIO1 of the SOC is configured as an output port of the SOC, the GPIO1 of the MCU is configured as an input port of the SOC, and the GPIO1 of the SOC is connected with the GPIO1 of the MCU. The GPIO2 of the SOC is configured as an input port of the SOC, the GPIO2 of the MCU is configured as an output port of the SOC, and the GPIO2 of the SOC is connected with the GPIO2 of the MCU.

In some embodiments, the touch display 2571 may display a user setup menu interface in which a user may select an operation mode of the stylus detection apparatus 231, for example, the operation mode may include a normal operation mode and a threshold correction mode. The user may select one of the normal operation mode and the threshold correction mode at the user setting menu interface, and the SOC may configure the voltage of the IO port to be high or low according to the option of the user setting menu interface, and thereafter, the MCU reads the voltage of the IO port by polling and interrupting, and determines that the stylus detection device 231 enters the normal operation mode or the threshold correction operation mode according to the voltage of the IO port.

After the operation mode of the stylus detecting device 231 is determined, that is, after the detection threshold of the stylus detecting device 231 is determined, the MCU may read the infrared light intensity value of the SENSOR and compare with the detection threshold, where the detection threshold includes an upper limit and a lower limit, two states including an upper limit (indicating that the stylus has been placed in the accommodating device 232) greater than the detection threshold and a lower limit (indicating that the stylus has been taken out of the accommodating device 232) less than the detection threshold are configured to be high or low, and the SOC determines whether the stylus is placed in the accommodating device 232 by polling or interrupting the reading of the voltage change of the IO port.

In addition, communication is performed between MCU and SENSOR through I2C. After the system is powered on each time, the MCU configures a register of the SENSOR through the I2C bus, initializes the register, and sets an initial detection threshold value. After the initialization of the SENSOR is completed, the MCU reads the data acquired by the SENSOR through the I2C interface.

It can be seen that in the present embodiment, the display device is formed by the touch display 2571, the accommodating device 232, the stylus detecting device 231, and the controller respectively connected to the touch display 2571 and the stylus detecting device 231. Wherein the receiving means 232 is configured to receive a stylus. The stylus detecting means 231 is configured to detect whether the stylus is placed in the accommodating means 232. The controller is configured to: receiving a selection operation made by a user on the touch display 2571, and controlling the stylus detection apparatus 231 to switch from a current operation mode to a target operation mode corresponding to the selection operation in response to the selection operation, wherein the operation modes of the stylus detection apparatus 231 include a detection threshold adjustable mode and a detection threshold fixed mode. Therefore, the display device can select the working mode of the stylus detection device 231 according to the requirements of the user, so that the user can correct the detection threshold value of the stylus detection device 231 by selecting the required working mode, the corrected detection threshold value can be used for accurately judging whether the currently used stylus is placed in the accommodating device 232, even if the user replaces different styluses, only the detection threshold value needs to be corrected again, the touch display 2571 can be effectively linked with the currently used stylus, and the user experience is improved.

In some embodiments, the controller is further configured to: if the target operation mode is detected to be the first operation mode, the touch display 2571 is controlled to display the first prompting information to prompt the user to put the stylus into the accommodating device 232. If the stylus is put into the accommodating device 232, the first data detected by the stylus detecting device 231 is acquired. The touch display 2571 is controlled to display a second prompt message to prompt the user to take the stylus out of the accommodating device 232. If the stylus is taken out of the accommodating device 232, the second data detected by the stylus detecting device 231 is acquired. The first target detection threshold is determined according to the first data and the second data, and the stylus detection device 231 is controlled to adjust the detection threshold corresponding to the first working mode to the first target detection threshold.

Taking an infrared detection device as an example of the stylus detection device 231, the operation of the display apparatus is as shown in fig. 5:

first, the stylus detecting device 231 is powered on with the touch display 2571, and the MCU initializes the SENSOR register value and sets an initial detection threshold.

Next, the host software of the touch display 2571 decides whether to enter the normal operation mode or the threshold correction mode according to the current option of the user menu, and configures the voltage of IO1 to be high or low accordingly, for example, the high level enters the normal mode, and the low level enters the threshold correction mode.

When the MCU detects that the voltage of IO1 is at a high level, the MCU program works in a normal detection mode, circularly reads the real-time register value of the intensity value of the SENSOR infrared light, compares the real-time register value with a set threshold value, and configures the voltage of IO2 according to a comparison result.

When the MCU detects that the voltage of IO1 is at a low level, the MCU program works in a threshold correction mode, and at the moment, the UI interface of the touch display 2571 pops up prompt information to be operated by a user. Firstly, the user is prompted not to place the touch pen, under the condition that the touch pen is not placed is detected, the infrared light intensity value detected by the SENSOR is set as second data, after the touch pen is completed, the user is prompted to place the touch pen in the accommodating device 232, the SENSOR detects the infrared light intensity again, and the infrared light intensity value detected currently is set as first data. And then taking the first data as the upper limit of the first target detection threshold and the second data as the lower limit of the first target detection threshold, thereby completing the setting of the first target detection threshold, and then automatically entering a first working mode by the MCU, and detecting through the detection threshold in the first working mode.

Finally, the SOC detects the voltage of IO2 of the MCU to determine whether the stylus is placed in the accommodating device 232, for example, if the voltage of IO2 is at a low level, it is determined that the stylus is not detected in the accommodating device 232, and if the voltage of IO2 is at a high level, it is determined that the stylus is already placed in the accommodating device 232.

In some embodiments, the controller is further configured to: and acquiring a first correction value, and correcting the first data according to the first correction value to obtain corrected first data. And acquiring a second correction value, and correcting the second data according to the second correction value to obtain corrected second data. And determining a first target detection threshold according to the corrected first data and the corrected second data, wherein the corrected first data is the upper limit of the first target detection threshold, and the corrected second data is the lower limit of the first target detection threshold.

The first correction value may be a fixed value set by a user according to experience, and stored in a memory of the touch display 2571, and the controller may call the first correction value from the memory, and then correct the first data according to the first correction value, to obtain corrected first data. Similarly, the second data may be corrected according to the correction method of the first data.

In some embodiments, the controller is further configured to: if the target working mode is detected to be the second working mode, controlling the touch display 2571 to display a threshold selection interface; responding to touch operation made by a user on a threshold selection interface, and generating a second target detection threshold; the stylus detection means 231 is controlled to adjust the detection threshold corresponding to the second operation mode to a second target detection threshold.

For example, the threshold selection interface may include a plurality of detection threshold options, the user may obtain a detection threshold corresponding to the options by selecting the detection threshold options, if the user's touch operation is a touch operation performed by the user at the threshold selection interface, the controller may determine the detection threshold selected by the user as the second target detection threshold, and then the controller may control the stylus detection device 231 to adjust the detection threshold corresponding to the second operation mode to the second target detection threshold.

Fig. 6 exemplarily illustrates a method for detecting a stylus according to an embodiment, which may be applied to the display device of the above embodiment, and in particular, may be applied to a controller in the display device, that is, an execution subject of the method is a controller, and the method may include:

101. a selection operation made by a user on the touch display is received.

In some embodiments, after the touch display is powered on, a working mode selection interface for the touch pen detection device may be displayed, where the working mode selection interface may display option icons corresponding to different working modes, a user may select a required working mode by clicking the option icons on the working mode selection interface, and the controller may receive the option icons of the electrode of the user on the touch display, so as to obtain a selection operation result of the user.

102. In response to the selection operation, controlling the stylus detection device to switch from a current operation mode to a target operation mode corresponding to the selection operation, wherein the operation modes of the stylus detection device include a detection threshold adjustable mode and a detection threshold fixed mode.

In some embodiments, after receiving the selection operation of the user, the controller may generate a corresponding control instruction according to the selection result, and send the control instruction to the stylus detection device, so as to control the stylus detection device to switch to the target working mode corresponding to the control instruction. For example, the operation modes of the stylus detection device include a detection threshold adjustable mode and a detection threshold fixed mode, wherein the detection threshold adjustable mode includes: and if the controller receives the selection operation of selecting the fixed detection threshold mode by the user, the fixed detection threshold mode can be determined as the target working mode, and the touch pen detection device is controlled to be switched from the current working mode to the fixed detection threshold mode, so that the detection threshold of the touch pen detection device is adjusted. If the current working state of the touch pen detection device is the detection threshold fixed mode, the current working mode can be maintained. The first working mode and the second working mode can be threshold correction modes, the detection threshold fixing mode can be a normal working mode, and the detection threshold of the touch pen in the normal working mode is an initial threshold, namely a threshold set by a factory. If the user selects the detection threshold adjustable mode, the user can adjust the detection threshold of the touch control pen detection device in the mode.

In some embodiments, the detection threshold may be a value or a range, and may specifically depend on the stylus detection device used, which is not limited herein. For example, if the stylus detection device is a pressure detection device, the detection threshold may be a pressure threshold. If the stylus detection device is an infrared detection device, the detection threshold may be a specified range of infrared light intensity values.

If the pressure data is less than the pressure threshold, it may be determined that the stylus is being removed from the containment device.

In other embodiments, when a pressure detection device is used as the stylus detection device, the detection threshold may be a range of infrared light intensity values that includes an upper infrared light intensity value limit and a lower infrared light intensity value limit. If the controller detects that the infrared light intensity value acquired by the touch control pen detection device in the target working mode is smaller than the lower limit of the infrared light intensity value corresponding to the target working mode, the detection data can be determined to meet the detection threshold corresponding to the target working mode, and the touch control pen is determined to be placed into the accommodating device. If the infrared light intensity value is greater than the upper limit of the infrared light intensity value, the stylus can be determined to be taken out of the accommodating device.

It can be seen that, in this embodiment, by receiving a selection operation made by the user on the touch display; in response to the selection operation, the touch pen detection device is controlled to switch from a current working mode to a target working mode corresponding to the selection operation, wherein the working mode of the touch pen detection device comprises a detection threshold adjustable mode and a detection threshold fixed mode, so that a user can conveniently adjust the working mode of the touch pen detection device according to the requirement of the user through the touch display, and further adjust the detection threshold of the touch pen detection device. If the detection data collected by the touch pen detection device in the target working mode meets the detection threshold corresponding to the target working mode, determining that the touch pen is put into the accommodating device. Because the detection threshold is corrected according to the requirement of the user, for example, the user replaces the touch pen and adjusts the detection threshold to be suitable for the replaced touch pen, the adjusted touch pen detection device can accurately detect whether the touch pen currently used by the user is put into the accommodating device or not, effective linkage of the touch pen and the touch pen is ensured, and user experience is improved.

In some embodiments, if the touch display receives valid data that is not detected by the stylus detection device within a specified period of time after the user makes the placement confirmation operation, for example, the stylus detection device does not detect the data or the detected data is not within a preset valid range value, the controller may control the touch display to display information for reminding the user that the stylus is not placed into the accommodating device normally on the first interface, and the first interface may also display text information of "that the stylus is not placed into the accommodating device normally and that the stylus is to be placed again".

205. And controlling the touch display to display second prompt information so as to prompt the user to take the touch pen out of the accommodating device.

In some embodiments, after the first data is collected and stored, the controller may control the touch display to display a second interface, where the second interface includes second prompting information, where the second prompting information is used to prompt the user to take the stylus out of the accommodating device, as shown in fig. 9, a text "please take the stylus out of the accommodating device" may be displayed on the second interface of the touch display.

206. And if the stylus is taken out of the accommodating device, acquiring second data detected by the stylus detecting device.

As another example, the first correction value may be determined according to the first data, specifically, a preset ratio set by a user according to experience may be stored in the memory, and the controller may call the preset ratio from the memory, calculate a product of the preset ratio and the first data, and then use the product of the preset ratio and the first data as the first correction value.

And then determining a first target detection threshold according to the corrected first data and the corrected second data, wherein the corrected first data is the upper limit of the first target detection threshold, and the corrected second data is the lower limit of the first target detection threshold, so that the difficulty of judging whether the stylus is placed in the accommodating device or not by the stylus detection device is reduced, and the detection efficiency of the stylus detection device is improved.

In some embodiments, as shown in fig. 11, the method further comprises:

203A, if the target working mode is detected to be the second working mode, controlling the touch display to display a threshold selection interface.

As another example, the threshold selection interface may also include a stylus size input box into which a user may enter a numerical value via a virtual keyboard, and the controller may then translate the stylus size into a corresponding detection threshold.

The designated weight may be the same as the weight value of the original stylus of the touch display, and may be stored in the memory of the touch display in advance, and may be recalled from the memory by the controller.

For example, if the controller detects that the weight value is inconsistent with the specified weight value, it may determine that the weight value does not match the specified weight value and control the stylus detection apparatus to enter the first operation mode.

In another example, if the controller detects that the absolute value of the difference between the weight value and the specified weight value is greater than the preset value, it may be determined that the weight value does not match the specified weight value, and the stylus detection device is controlled to enter the first operation mode.

In some embodiments, steps 202A-202B may be performed prior to step 203.
